Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your cargo area.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
Powered Tail Light Converter with Surface-Mount Technology
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Fairly easy to install. Just plugs in. Only complaint is the driver's side wiring harness is about 6" short in my opinion. The control box lays on top of bumper support because the harness wasn't long enough to allow control box to come down to be mounted like instructions said. The bumper support on the Kia is an open matrix structure, so there isn't anyplace to mount the box to on top. If the harness was 6" longer, it could have been solid mounted to the forward facing side of the bumper support.

Nice harness easy to install and the directions were accurate

This worked perfectly and was easy to install. One year later and it still works great.
by: MikeyDog11/10/2022
This wiring kit makes the job much easier. Like others though, I do wish Curt would a few inches of wire to the passenger side of the harness. All connections fit like factory.

It was so easy to find the correct trailer hitch / tow package I needed for my car! The order came very fast, and the staff were very quick to respond to my questions! I returned one item (my husband wanted to get a different one for his car), and thy were super helpful with the return as well as the new item!! Overall, it was a great and easy experience!!

by: Don F.07/23/2020
Works well. Some problems with the fuse adaptor that pulled out of its connector. I have to hot-wire it, but I can deal with that.

Wiring harness installs rather easily. It would be better if the wires were longer going from the driver side tail light connection to the module to allow more room for attaching it to the chassis.

I have reordered the right harness. I received the wrong information from the car dealer I bought the vehicle from. Tyler was very helpful with my reorder. I don’t have the hitch on yet so no pics at this time.
by: Clay 06/13/2020
Super easy installation, got the wiring done in 20 minutes and everything works perfectly. The only complaint I have is that I paid for two day shipping and got it in three days. Don’t know whose fault this is but when a person pays for something expedited the expect to get what they pay for, otherwise could t be happier.

- Why Would Trailer Wiring Have Brake Lights Active All the TimeThis is typically a sign that the converter box of your trailer wiring kit is shorted out and in need of replacing. The converter boxes are designed to "fall on the sword" of a trailer short and act as a one time fuse that prevents the short from potentially affecting the vehicle wiring.
view full answer... - Comparing 4-Pole Wiring Harness Kits for 2013 Ford EscapeThe Curt # C56328 and Tow Ready # 118566 4-pole wiring harnesses that fit your 2013 Ford Escape are very similar powered-type wiring kits. They both include all of the parts required for installation and both are mostly plug-in type products. Both only require you to run one single wire up to the engine compartment, the wire that brings the 12V power to the harness to operate the trailer's lights. Both will protect your Escape's wiring from the risk of a short-circuit that could be caused...

- Wiring Harness Install Video for 2012 Kia Sorento Base I4While we do have a video of a trailer wiring harness installation on a 2012 Kia Sorento, it is not for the Curt T-Connector Vehicle Wiring Harness # C56328. Instead, the video we have, which I have linked for you below, is of an installation of the Tekonsha T-One Vehicle Wiring Harness # 118506. Between the two harnesses, I highly recommend going with the Tekonsha for your 2012 Sorento. Not only have they proven to have the far more reliable harnesses, it also has the highest amp rating...
view full answer... - What is the Correct Trailer Wiring harness for a 2012 Kia Sorento 4 CylinderThe correct wiring harness for a 4 cylinder 2012 Kia Sorento is # C56328. The other kit you have referenced, # 118506, is not a verified fit for the 4 cylinder 2012 models. I have included a link to the installation instructions for you to view.

The wiring kit 56151 that you referenced in your question is only compatible with the 6 cylinder 2012 Kia Sorento LX. For the Curt Wiring Harness # C56163, you will simply install the connectors behind your tail light housing and run the 12V power wiring up to your battery. I have attached a video of the similar...
view full answer... - Troubleshooting Turn Signal and Brake Lamp Circuit in Trailer Taillight WiringThe first thing you'll want to check is the trailer connector on the vehicle. You can use a circuit tester like # PTW2993 on the pins for the right/left turn as a helper activates them. If you're getting signal for right/left turn and the brake lamps on the pins of the 4-pole trailer connector fed by the yellow and the green wires, then the problem exists in the trailer wiring. If you're not getting signal on those pins, be sure that the taillight converter harness has been plugged in...
view full answer... - Recommended Towing Package For 2011 Kia Sorento 4 CylinderIf your 2011 Kia Sorento does not have the dual exhaust system with a tailpipe on both the driver and passenger side, I recommend the Draw-Tite Class ll Hitch, part # 36511. This hitch has a 1-1/4 inch receiver opening. I have attached an installation video for this hitch on a Sorento you can check out. You may be interested in a Draw-Tite Ball Mount like part # 36051. This drawbar provides a 5/8 inch rise or a 1-1/4 inch drop and measures 7 inches from the center of the hitch pin hole...

In order to tow a trailer with your Sorento, you will need a hitch receiver such as the Curt Trailer Hitch Receiver part # C13073, which will fit models with and without the towing package. You will also need a trailer wiring harness to attach to your factory harness such as the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package part...
view full answer... - Trailer Wiring Harness Recommendation for a 2012 Kia SorentoThe main difference between the Curt Modulite Wiring Harness, # C59496, and the Curt T-Connector Wiring Harness, # C56328, is that the T-Connector harness, # C56328, simply plugs into the factory tail light connectors at the back of the tail light assemblies. The Modulite Harness, # C59496, needs to be hardwired into your vehicles tail light circuits. I recommend using the T-Connector Harness # C56163 because you will not need to cut or splice into your vehicles tail light wires. Both...
view full answer... - Side Marker Lights and Tail Lights Stopped Working on 2004 Aliner Sport TrailerIt sounds to me like you may actually have a ground problem. Often if a trailer has a weak or marginal ground connection it will be able to pass enough current for the lower current draw lights, such as the turn signals, but not enough for the side marker and taillights which are always on. To begin the troubleshooting, I would start with the easiest step first and check the connectors on both your 2012 Kia Sorento LX and the trailer. Make sure that they are clean and free of dirt and corrosion...
view full answer... - Best Trailer Wring Options for 2011 Kia Sorento EX V6 AWDThe trailer wiring harness you need will depend on whether or not your Sorento is equipped with the factory tow package. If you have the tow package, I'd recommend part # HM11143965. Without the tow package, use part # 118506. With the correct harness, you will be all set. I've linked you to some installation videos that you might find helpful.
view full answer... - Trailer Wiring 4-Way Kit for 2012 Kia Sorento without Tow PackageSince your 2012 Kia Sorento didn't come with a factory hitch it's a safe assumption you don't have the factory tow package for picking out trailer wiring. If you have an EX or LX model you'd want the part # C56328 or if you have an SX model you'd want the part # C59236.
view full answer... - Trailer Wiring Harness Options for a 2012 Kia Sorento EXThere are 2 different wiring harnesses available for the 2012 Kia Sorento. If you have a V6 model with a factory towing prep package, you can use harness # C56332 that you referenced. It will only fit the V6, towing prep models. If you have a 4 cylinder model, you would need to use # C56328. I have included links to the installation instructions for both kits for you.

We also have detailed instructions and a video showing how to install this kit, see links. The vehicle in the video is different,...
view full answer... - Trailer Wiring Harness for 2011 Kia SorentoThe correct Curt trailer taillight wiring harness will depend on if your Sorento is equipped with the factory tow package. If it doesn't have the tow package, use # C56328, unless it's the SX model, which would use the # C59236. If it does have the tow package, it would use # C56332. The Curt # C56131 you'd looked at is a fit for the Kia Forte, and wouldn't work on your Sorento. I've linked to some installation videos that you might find helpful.

No hitch for your Escape avoids this and we do not have a relocation kit for the sensors. At least one hitch maker is investigating this possibility but no products/kits are available yet. You'll still be able to operate the auto lift gate by triggering one of the side sensors. To...
view full answer... - Is Draw-Tite Trailer Hitch 75684 For 2011 Kia Sorento a Class 3 or Class IV Hitch?The Draw-Tite # 75684 you were looking at is a Class 3 hitch, not a class IV and would be the correct option for your 2011 Kia Sorento. If you're going to be towing you'll also want to pick up a wiring harness # C56332 if you have the factory tow package v6 engine, or # C56328 if you have an I4 engine.
